Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been running.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect the fuel pressure gauge and turn the ignition to the "ON" position without starting the engine.
3. Record the fuel pressure reading; it should typically be between 40-50 psi.
4. If pressure is low, inspect the fuel pump and fuel filter for blockages or failures.

3. Throttle Body Cleaning

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use a throttle body cleaner and a soft cloth to wipe down the inside of the throttle body.
3. Ensure the throttle plate opens freely and does not stick.
4. Reattach the intake duct securely.

4. Ignition Component Replacement

Sub-steps:
1. Remove the engine cover to access the ignition coils.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the bolts securing the ignition coils and take them out.
4. Replace any faulty spark plugs and ignition coils with new ones.
5. Reinstall the components in reverse order and ensure all connections are secure.

5. MAF Sensor Cleaning or Replacement

Sub-steps:
1. Locate the MAF sensor in the intake air duct.
2. Disconnect the electrical connector and remove the sensor from the duct.
3. Clean the MAF sensor using a dedicated MAF cleaner.
4. Allow it to dry completely and reinstall it, or replace it if damaged.
